Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at Filters in ASP.NET MVC. It's our 9th tutorial in ASP.NET MVC series. It's also a new concept which is essential to discuss as it's used almost in every form submission.
We have already understand Controllers in ASP.NET MVC and we know that Controllers have action methods in it which are directly assigned to respective Views, which are then displayed to the user. But in some cases, we have to place some checks (called Filters) before or after this action method called. So, let's have a look at these Filters in ASP.NET MVC in detail:
Filters in ASP.NET MVC
Filters are attributes which we can use before or after action method called in a Controller.

We're glad you could join us for another lesson in our series on programming for the Raspberry Pi 4. The previous chapter covered how to interface the USB barcode scanner with raspberry pi 4. We looked at different types of barcodes and what each stripe represents as well as the different types of barcode scanners available today. We also built a python program for the intelligent shopping cart and now our familiarity with barcodes and scanners and how they function has significantly increased. The benefits and drawbacks of its use were also discussed, but what we're interested in for this article is the transmission of radio frequency signals using the nrf24l01 Module in a raspberry pi 4.

Hello friends, I hope you all are having fun. In today's tutorial, we will have a detailed Introduction to Inheritance in C#. It's our 15th tutorial in C# series and again an important concept in Object Oriented Programming, as it helps in code optimization.
In our previous tutorial, we have discuss namespaces in C# and that was the last storage item in C#. Today, we are dealing with entirely different entity, which is inheritance. So, let's discuss it in detail:
Introduction to Inheritance in C#
Inheritance in C# is used to create a relation between two classes. In simple words, derived / child class is inherited from base / parent class and will automatically have all its members as its own. Inheritance is denoted by ( : ).

Welcome to the next lesson of our python programming class. In the last session, we looked at the use of If-else statements and created simple programs to demonstrate the concept. While loops are another type of conditional statement, and in this tutorial, we'll look at how they're used.
What will you learn?
In this article, you'll learn how to prematurely exit a while loop, a Python control structure for endless iteration. You will also learn how to write conditions in a single line to produce short and readable code.
Iteration in while loop
The term "iteration" refers to the practice of repeatedly running the same piece of code. A loop is a type of programming structure that implements iteration.

Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create Views in ASP.NET Core MVC. It's our 8th tutorial in ASP.NET Core series. In our 6th lecture, where we have set up MVC architecture, we have also created Controller & Model, but we haven't yet created any View to display this data properly.
We have also seen Dependency Injection and have successfully injected Model Interface in our Home Controller. So, now it's time to add a View in our project and communicate it with Controller & Model. So, let's get started with Views in ASP.NET Core MVC:
